Can you afford a lunch at Eiffel Tower?

Hi! My wife and I are on our second honeymoon, again in Paris. Last time we had great time and saw some great things, but we missed to eat in restaurant in Eiffel Tower. I wonder, would it be expensive to take my wife to lunch one day, like a surprise? I heard from some French man on the market that we may wait in line to get served. Any tips or suggestions?

I suggest you to pay for Cin d'Oeil tour of Paris. Driver and guide will drop you off at the foot of the Eiffel Tower for lunch, at "Altitude 95". This restaurant is situated on the 1st Floor. You will take the elevator (without waiting in line, which may be extremely long in the summer) straight to the restaurant. A table will be already reserved under your name. If you don't go with the tour, you will wait in line at least an hour and maybe wait in line in restaurant, cause it's always overcrowded. And yes, it' very expensive!
